Php 如何检查某个对象ID是否为页面或帖子(从页面/帖子本身外部)_Php_Wordpress - Fatal编程技术网

Php 如何检查某个对象ID是否为页面或帖子(从页面/帖子本身外部)

Php 如何检查某个对象ID是否为页面或帖子(从页面/帖子本身外部),php,wordpress,Php,Wordpress,我有一个导航菜单循环,它使用一个自定义walker,输出: <ul> <li id="menu-item-2" class="menu-item-object-category">stuff</li> <li id="menu-item-3" class="menu-item-object-category">stuff</li> ... etc And if a page is in the menu, it outputs: <

我有一个导航菜单循环,它使用一个自定义walker,输出:

<ul>
<li id="menu-item-2" class="menu-item-object-category">stuff</li>
<li id="menu-item-3" class="menu-item-object-category">stuff</li>
...
etc
And if a page is in the menu, it outputs:
<li id="menu-item-4" class="menu-item-object-page">stuff</li>
</ul>
我尝试了is_page(),但意识到这是一个布尔函数,用于检测当前页面是否为页面

是否有任何简单的方法可以检查walker中的每个输出页面

这是我的沃克密码:

class Custom_Walker extends Walker_Nav_Menu
{ 
    function start_el(&$output, $item, $depth, $args) {
        global $wp_query;

        $indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';

        $class_names = $value = '';

        $classes = empty( $item->classes ) ? array() : (array) $item->classes;

        $class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
        $class_names = ' class="' . esc_attr( $class_names ) . '"';

        $output .= $indent . '<li id="menu-item-'. $item->ID . '"' . $value . $class_names .'>';

        $attributes  = ! empty( $item->attr_title ) ? ' title="'  . esc_attr( $item->attr_title ) .'"' : '';
        $attributes .= ! empty( $item->target )     ? ' target="' . esc_attr( $item->target     ) .'"' : '';
        $attributes .= ! empty( $item->xfn )        ? ' rel="'    . esc_attr( $item->xfn        ) .'"' : '';
        $attributes .= ! empty( $item->url )        ? ' href="'   . esc_attr( $item->url        ) .'"' : '';

        $item_output = $args->before;

                $item_output .= '<a'. $attributes .'>';
        $item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;

        $item_output .= '</a>';
        $item_output .= $args->after;

        $output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );

    }
}

  • 谢谢

    您可以使用函数并检查类型,例如:

    <?php
    
    $current_post = get_post($current_post_id);
    if ($current_post->type == 'post') {
      //Do the stuff with post
    }
    elseif ($current_post->type == 'page') {
      //Do the stuff with page
    }
    else {
      //Do the stuff with other post types
    }
    
    必须是if($current\u post->post\u type=='page'),但除此之外,这正是我需要的,谢谢!
    
    <?php
    
    $current_post = get_post($current_post_id);
    if ($current_post->type == 'post') {
      //Do the stuff with post
    }
    elseif ($current_post->type == 'page') {
      //Do the stuff with page
    }
    else {
      //Do the stuff with other post types
    }
